Help Wiring Juwel Light Ballast

[jamesmacc]

hey folks, bulbs were flicking on my rio180 so i vcut it open to find the ballast to get a part number etc. i have found one on ebay that is 2x30w t8 like mine but it has 6 wires and not 3 like mine, my tubes seem to share an earth and have a live for each of them. here is the bllast i found http/api.viglink.com/api/click?format=go&key=dd1565d9a6e3794e62d9582c3ccfe600&loc=http%3A%2F%2Fwww.fishforums.net%2Findex.php%3F%2Ftopic%2F265546-fixing-juwel-light-bar%2Fpage__st__140&v=1&libid=1329910516327&out=http%3A%2F%2Fwww.ebay.co.uk%2Fitm%2FTRIDONIC-ATCO-2-x-30W-T8-HF-ELECTRONIC-BALLAST-%2F220954495696%3Fpt%3DUK_Pet_Supplies_Fish%26hash%3Ditem3371ea0ad0&ref=http%3A%2F%2Fwww.fishforums.net%2Findex.php%3Fapp%3Dcore%26module%3Dsearch%26do%3Duser_activity%26mid%3D82439&title=Fixing%20Juwel%20Light%20Bar.%20-%20Tropical%20Fish%20Forums%20-%20Page%208&txt=http%3A%2F%2Fwww.ebay.co.u...%3Ditem3371ea0ad0&jsonp=vglnk_jsonp_13299105257051

here is the new ballast with the old wires, you can see that two tubes are connected by 1 wire and the other end has one wire each. so i have 3 wires but 6 terminals on the new ballast

I've just had an absolute ball ache doing the same with an Arcadia unit. Took me two hours and a lot of growling and swearing! in the end I just ignored the existing set up and concentrated on what the new ballast wanted. The existing setup just confused things as I'd trying and justify why the new one want something different; in the end I just had to forget about it and concentrate on the picture on the new one.

so i might have to rewire it? think i might just ditch it and get some leds, dont want to spend £70 on a new unit as im going to sell the tank
